Yes, anything that gives off light e.g. the sun is luminous. So would be a lamp and the moon, however not all things e.g. Not a mirror, not a table and not a piece of paper.

well they eyes are like our eyes they can get blind

∙ 14y agoYes it is. Electrical energy going into the bulb is converted into light and heat energy.

∙ 11y agoTechnically, no. The lightbulb in the lamp emits light, not the lamp itself.

What is luminous color?
Luminous colours are bright and kind of glow in the dark like a hivise and these are the luminous colours: luminous pink Green Yellow Blue Orange
how can a flashlight be both luminous and non-luminous at the some time?
A flashlight is luminous when it emits light (turned on). It's non-luminous when it's off or the battery dies.
What are the similarities of luminous and non-luminous?
They both produce heat
What are the advantages of using a non-luminous flame?
Non- Luminous can burn efficiently because luminous flames don't burn as efficiently as non-luminous ones, they don't produce as much energy. This means that the non-luminous flames have a lot more energy than luminous ones, and their flames are actually hotter. This is why the luminous ones look yellow and the non-luminous ones look blue. Hotter flames burn blue and (relatively) cooler ones burn yellow.
Should a luminous or non luminous Bunsen flame be used for heating in the laboratory and why?
Non-luminous flame should be used for heating in the laboratory because the flame is steady and produce little or no soot.Non-luminous flame is very hot thus, it is recommendable to use for laboratory purposes.Luminous flame is unsteady while non-luminous flame is steady.Another reason of using non-luminous flame because the flame of non-luminous is blue, and not visible unlike the luminous flame which is yellow in colour and visible.
When a lamp is turned off is it luminous or non-luminous?
If the bulb is switched off, then we would call it non-luminous.
Luminouse objects produce what kind of light?
Luminous objects usually give out the light that they make on their own. An example of a luminous object is a star or an LED lamp.
What are two examples of a luminous source that produces a line spectrum?
1. Glow discharge lamp 2. Electrode discharge in spectrometry
Is a lamp luminous or non luminous?
Planets( Mercury, Venus, Earth, Jupiter, Saturn, Uranus, Neptune) and also Moons are Non-Luminous objects they don't emit light. The reason we see them because they reflect light from the Sun.
How many lumen in a 25 watt incandescent light bulb?
a 100W incandescent lamp emits 120 candela.lumen is the unit for luminous intensity per steradian ,an lamp emits in all directiontherefore a 16.25watt lamp contains 19.5 lumenAnswerThe lumen is the SI unit for luminous flux -which describes the output power of visible light expressed in photometric units. The ratio of a lamp's output luminous flux to its input power is termed 'efficacy', expressed in lumens per watt. The efficacy for incandescent lamp varies from 5-15 lumens per watt. So the output of a 16.25-W incandescent lamp will be between 80-245 W.
Is lamps is luminous?
Yes, anything that gives off light e.g. the sun is luminous. So would be a lamp and the moon, however not all things e.g. Not a mirror, not a table and not a piece of paper.
What is the main difference of Bunsen burner to alcohol lamp?
Alcohol lamp- is used as a source of heat and light . Bunsen burner- source of heat when non-luminous flame is needed for experimental work..
What is an astral lamp?
An astral lamp is a type of oil lamp that produces a bright and steady flame. It is often used for decorative purposes or as a source of light in outdoor settings. The term "astral" refers to its ability to produce a luminous and ethereal light.
Formula between Current and luminous intensity?
Any formula relating those two quantities must depend on the technique used to generate light by means of electric current. We know that there can't be one universal formula because, for example, we know that a compact fluorescent lamp uses less current to produce more luminous intensity than an incandescent lamp.
Is a volcano erupting luminous or non luminous?
It is luminous
Is sooty flame a luminous or non luminous?
luminous
Is the earth luminous or non-luminous?
The earth is Non-luminous.
